No way.... the DS Lite isn't too top heavy.

Make a DS Lite with Treo thumbboard (same size keys, but just a tad more space between keys for those with large thumbs) in place of the touch screen. Keep D-Pad & gaming buttons (A,B,X,Y) to the side of the thumbboard. Top screen would be a touchscreen with virtually no border.... and hopefully this clamshell could flip around to be turned into tablet mode. With 5-way somewhere right next to the screen, like N800 (I'm honestly not even considering an N810 because of this and the lack of SD slots). I use the 5-way much more than I use touchscreen on my Treo. I feel like all smartphones & MIDs that want to have hardware keyboards need to take notes from the Treos' keyboard & 5-way pad integration with sofware.

Something like the Pandora but with smaller form factor & screen that can rotate into tablet mode with 5-way next to screen, & SIM slot.

They thumbboard is key, tho!! Treos have done this right for 4+ years!!! And companies, starting with HTC decided that slider thumbboards that had FLAT keys RIGHT next to each other were the greatest idea ever. Go back to the drawing boards, guys!!

Ahhh.... I'll never find a device worth my money.
